What will Kate Middleton wear on her wedding day?

"All we have been told is that the dressmaker is fairly unknown and from a relatively small design house. But make no mistake, whoever's name emerges on the day, this is very much Catherine's dress," a source told MailOnline.

However, Yvonne Yorke, Huffington Post Royal Correspondent, first broke the world-exclusive four months ago, hinting on a "young, little-known British female designer who had worked with Catherine before."

"Sophie Cranston, of the low-key label Libelula, was tipped as the creator of the wedding dress," reports Yorke in her more recent Huff Post. And the soon-to-be royal has helped design it.

Cranston is said to have not been announced as the designer in order to protect her and her family "from media scrutiny for as long as possible, and to allow her the freedom to create the wedding gown of Catherine's dreams without additional pressures and distractions," explained Yorke.

The 34-year-old has won the Designer of Year award at London's Graduate Fashion Week in 1999 and has previously worked for Alexander McQueen and Alice Temperley.

Though the dress will not be unveiled until the day of the Royal Wedding, it's said to be ivory satin and lace with a pearl button detail and a 10ft train.

Middleton is planning to wear diamond-and-pearl earrings, and is planning to borrow Queen Elizabeth's, William's grandmother, jewellery including a tiara.

"She is a lovely person with a beautiful body. I like her nose," said Karl Lagerfield, Chanel designer, praising the princess in waiting.

"I will be commenting on French TV. Royalty is good for the crowd."

However, he does not seem to be marriage material...

"Marriage was invented when people died at 30. Now they marry at 30 and they have to do it for 60 years," he told The Sunday Times Style magazine.

"The idea that you will never look at anyone else, that is a problem."

And while you may not have gotten an invite to the big day, Westminster Abbey is making sure you do not miss it with a launch of a new 'Royal App' that offers a "super realistic tour."

"Westminster Abbey has released a new app ahead of the Royal Wedding, giving users the chance to virtually tour the Abbey," reports Clarence House.

"The first official 'Royal App' telling the story of seven royal weddings from 1840 to 2005 is now available to download," tweets Clarence House.

"It uses the latest laser scanning technology combined with 3D modelling to create a super realistic version of the Abbey, a technique commonly used in film production but rarely applied to mobile devices," says Westminster Abbey's press release.
